Pre-emptive triggering for integrated access and backhaul for 5g or other next generation network

ABSTRACT

In a 5G network, a pre-emptive scheduling request (SR) and a pre-emptive buffer status report (BSR) can be used to reduce the latency of data transmissions on the upstream of a multi-hop integrated access and backhaul (IAB) network from the user equipment UE to the IAB-donor node. A centralized unit (CU) can uniformly ensure that the pre-emptive SR/BSR feature is turned on or off across the entire IAB network regardless of which vendor provides the IAB nodes. Additionally, a message can be sent from a gNodeB to the CU to the IAB node to indicate whether the pre-emptive SR/BSR triggering feature is turned on or off.

TECHNICAL FIELD

This disclosure relates generally to pre-emptive triggering integratedaccess and backhaul networks for a 5G new radio (NR) networks.

BACKGROUND

5^(th) generation (5G) wireless systems represent a next major phase ofmobile telecommunications standards beyond the currenttelecommunications standards of 4^(th) generation (4G). Rather thanfaster peak Internet connection speeds, 5G planning aims at highercapacity than current 4G, allowing a higher number of mobile broadbandusers per area unit, and allowing consumption of higher or unlimiteddata quantities. This would enable a large portion of the population tostream high-definition media many hours per day with their mobiledevices, when out of reach of wireless fidelity hotspots. 5G researchand development also aims at improved support of machine-to-machinecommunication, also known as the Internet of things, aiming at lowercost, lower battery consumption, and lower latency than 4G equipment.

The above-described background relating to facilitating pre-emptivetriggering for integrated access and backhaul networks is merelyintended to provide a contextual overview of some current issues, and isnot intended to be exhaustive. Other contextual information may becomefurther apparent upon review of the following detailed description.

It should be noted that although various aspects and embodiments havebeen described herein in the context of 5G, Universal MobileTelecommunications System (UMTS), and/or Long Term Evolution (LTE), orother next generation networks, the disclosed aspects are not limited to5G, a UMTS implementation, and/or an LTE implementation as thetechniques can also be applied in 3G, 4G or LTE systems. For example,aspects or features of the disclosed embodiments can be exploited insubstantially any wireless communication technology. Such wirelesscommunication technologies can include UMTS, Code Division MultipleAccess (CDMA), Wi-Fi, Worldwide Interoperability for Microwave Access(WiMAX), General Packet Radio Service (GPRS), Enhanced GPRS, ThirdGeneration Partnership Project (3GPP), LTE, Third Generation PartnershipProject 2 (3GPP2) Ultra Mobile Broadband (UMB), High Speed Packet Access(HSPA), Evolved High Speed Packet Access (HSPA+), High-Speed DownlinkPacket Access (HSDPA), High-Speed Uplink Packet Access (HSUPA), Zigbee,or another IEEE 802.XX technology. Additionally, substantially allaspects disclosed herein can be exploited in legacy telecommunicationtechnologies.

Described herein are systems, methods, articles of manufacture, andother embodiments or implementations that can facilitate pre-emptivetriggering for integrated access and backhaul networks for a 5G network.Facilitating pre-emptive triggering for integrated access and backhaulnetworks for a 5G network can be implemented in connection with any typeof device with a connection to the communications network (e.g., amobile handset, a computer, a handheld device, etc.) any Internet ofthings (IOT) device (e.g., toaster, coffee maker, blinds, music players,speakers, etc.), and/or any connected vehicles (cars, airplanes, spacerockets, and/or other at least partially automated vehicles (e.g.,drones)). In some embodiments the non-limiting term user equipment (UE)is used. It can refer to any type of wireless device that communicateswith a radio network node in a cellular or mobile communication system.Examples of UE are target device, device to device (D2D) UE, machinetype UE or UE capable of machine to machine (M2M) communication, PDA,Tablet, mobile terminals, smart phone, laptop embedded equipped (LEE),laptop mounted equipment (LME), USB dongles, etc. Note that the termselement, elements and antenna ports can be interchangeably used butcarry the same meaning in this disclosure. The embodiments areapplicable to single carrier as well as to multicarrier (MC) or carrieraggregation (CA) operation of the UE. The term carrier aggregation (CA)is also called (e.g., interchangeably called) “multi-carrier system”,“multi-cell operation”, “multi-carrier operation”, “multi-carrier”transmission and/or reception.

In some embodiments the non-limiting term radio, network node, or simplynetwork node is used. It can refer to any type of network node thatserves UE is connected to other network nodes or network elements or anyradio node from where UE receives a signal. Examples of radio networknodes are Node B, base station (BS), multi-standard radio (MSR) nodesuch as MSR BS, eNode B, network controller, radio network controller(RNC), base station controller (BSC), relay, donor node controllingrelay, base transceiver station (BTS), access point (AP), transmissionpoints, transmission nodes, RRU, RRH, nodes in distributed antennasystem (DAS), etc.

Cloud radio access networks (RAN) can enable the implementation ofconcepts such as software-defined network (SDN) and network functionvirtualization (NFV) in 5G networks. This disclosure can facilitate ageneric channel state information framework design for a 5G network.Certain embodiments of this disclosure can comprise an SDN controllerthat can control routing of traffic within the network and between thenetwork and traffic destinations. The SDN controller can be merged withthe 5G network architecture to enable service deliveries via openapplication programming interfaces (“APIs”) and move the network coretowards an all internet protocol (“IP”), cloud based, and softwaredriven telecommunications network. The SDN controller can work with, ortake the place of policy and charging rules function (“PCRF”) networkelements so that policies such as quality of service and trafficmanagement and routing can be synchronized and managed end to end.

To meet the huge demand for data centric applications, 4G standards canbe applied 5G, also called new radio (NR) access. 5G networks cancomprise the following: data rates of several tens of megabits persecond supported for tens of thousands of users; 1 gigabit per secondcan be offered simultaneously to tens of workers on the same officefloor; several hundreds of thousands of simultaneous connections can besupported for massive sensor deployments; spectral efficiency can beenhanced compared to 4G; improved coverage; enhanced signalingefficiency; and reduced latency compared to LTE. In multicarrier systemsuch as OFDM, each subcarrier can occupy bandwidth (e.g., subcarrierspacing). If the carriers use the same bandwidth spacing, then it can beconsidered a single numerology. However, if the carriers occupydifferent bandwidth and/or spacing, then it can be considered a multiplenumerology.

The decision to trigger a pre-emptive scheduling request (SR) or bufferstatus report (BSR) and the actions taken by an integrated access andbackhaul (IAB) node upon receiving a pre-emptive SR/BSR can be left upto implementation, such that each individual IAB node can decideindependently whether or not to turn on the pre-emptive SR/B SRfunctionality for latency-sensitive traffic. Furthermore, there iscurrently no central mechanism being designed to control thefunctionality of pre-emptive SR/BSR triggering. This also means thatwhen an operator's network has IAB nodes from different vendors, thereis no way for an operator to ensure that pre-emptive SR/BSR triggeringis turned on or off. Even though the actual triggering and actions takenrelated to pre-emptive SR/BSR can be performed in a proprietary mannerby each IAB vendor, there can be certain scenarios in which an operatoror gNB-centralized unit (CU) may want the pre-emptive SR/BSR to beturned off. Currently, there is no solution to turn off pre-emptive SR/BSR if needed. One situation where the pre-emptive SB/BSR can be turnedoff is to test the feature to assess its performance impact. Anotherreason could be to turn it off in order to troubleshoot some performancefeatures in the network. Still another reason could be that a gNB-CUcould be operating across a pool of IAB nodes that are manufactured bydifferent vendors, and the vendors' implementation of this feature maynot be consistent with each other, causing some performance issues inone part of the network versus another. Yet another reason for thegNB-CU to consider turning off pre-emptive SR/B SR is wastage of radioresources. If the IAB node triggers pre-emptive SR/B SR prematurely, itcan receive grants from its parent node before it has received data fromits child node. This can cause allocated radio resources to gounutilized causing wastage. If a gNB-CU determines that an IAB node iscausing too much wastage of resources, due to premature pre-emptiveSR/BSR triggering, it can turn of the feature.

In one embodiment, for the gNB-CU-CP to control the pre-emptive SR/BSRtriggering feature, it is proposed that a message can be sent from thegNB-CU-CP to the IAB node to indicate whether the pre-emptive SR/BSRtriggering feature is turned on or off. The indication can apply to allbearers or backhaul RLC channels supported by the IAB node, and/or canbe indicated separately for each bearer or backhaul RLC channel onwhether N:1 or 1:1 bearer mapping is supported in the network. Inanother embodiment, the message to turn on/off (e.g., active/inactive)the pre-emptive SR/BSR feature, from the gNB-CU-CP to the IAB node, canbe delivered via a message on the F1-AP interface to the donor unite(DU) residing on the IAB node. In this case, since this message is notspecifically related to a particular UE, this F1-AP message can be anon-UE-associated F1-AP message. In another embodiment, it is alsopossible that the gNB-CU-CP can send such a message to the MT residingon the IAB node. In this case, this message would be sent via RRCsignaling to the mobile terminal (MT) of the IAB node. In anotherembodiment, the configuration of the pre-emptive SR/BSR feature can beprovided via higher layer signaling, but the indication of the use ofthe feature at a child IAB node can be sent dynamically orsemi-persistently via downlink control information (DCI) or media accesscontrol (MAC) control element (CE). This can be beneficial in case thepre-emptive SR/BSR feature utilizes different signaling (e.g. a new MACCE) compared to the regular SR/BSR.

In one embodiment, described herein is a method comprising receiving, bya first wireless network device comprising a processor from a secondwireless network device, scheduling request data representative of ascheduling request to send data via an uplink channel of a wirelessnetwork. In response to the receiving the scheduling request data, themethod can comprise, sending, by the first wireless network device, thescheduling request data to a third wireless network device.Additionally, in response to the sending the scheduling request data tothe third wireless network device, the method an comprise receiving, bythe first wireless network device from the third wireless networkdevice, uplink grant data representative of a grant for the secondwireless network device to send the data to the third wireless networkdevice via the first wireless network device.

According to another embodiment, a system can facilitate receiving, by afirst node device of a wireless network from a mobile device of thewireless network, scheduling request data representative of a schedulingrequest to transmit packet data. In response to the receiving thescheduling request data, the system can facilitate transmitting thescheduling request data to a second node device of the wireless network.Furthermore, in response to the transmitting the scheduling request datato the second network node device, the system can comprise receivinggrant data representative of a grant for the mobile device to transmitthe packet data to the second network node device.

According to yet another embodiment, described herein is amachine-readable storage medium that can perform the operationscomprising facilitating receiving, from a mobile device of a wirelessnetwork, scheduling request data representative of a request to sendpacket data. In response to the facilitating the receiving thescheduling data, the machine-readable storage medium can perform theoperations comprising facilitating sending the scheduling data to anetwork node device. Furthermore, in response to the facilitating thesending the scheduling data to the network node device, themachine-readable storage medium can perform facilitating receivinguplink grant data representative of a grant to send the packet data tothe network node device.

These and other embodiments or implementations are described in moredetail below with reference to the drawings.

Referring now to FIG. 1, illustrated is an example wirelesscommunication system 100 in accordance with various aspects andembodiments of the subject disclosure. In one or more embodiments,system 100 can comprise one or more UEs 102. The non-limiting term userequipment can refer to any type of device that can communicate with anetwork node in a cellular or mobile communication system. A UE can haveone or more antenna panels having vertical and horizontal elements.Examples of a UE comprise a target device, device to device (D2D) UE,machine type UE or UE capable of machine to machine (M2M)communications, personal digital assistant (PDA), tablet, mobileterminals, smart phone, laptop mounted equipment (LME), universal serialbus (USB) dongles enabled for mobile communications, a computer havingmobile capabilities, a mobile device such as cellular phone, a laptophaving laptop embedded equipment (LEE, such as a mobile broadbandadapter), a tablet computer having a mobile broadband adapter, awearable device, a virtual reality (VR) device, a heads-up display (HUD)device, a smart car, a machine-type communication (MTC) device, and thelike. User equipment UE 102 can also comprise IOT devices thatcommunicate wirelessly.

In various embodiments, system 100 is or comprises a wirelesscommunication network serviced by one or more wireless communicationnetwork providers. In example embodiments, a UE 102 can becommunicatively coupled to the wireless communication network via anetwork node 104. The network node (e.g., network node device) cancommunicate with user equipment (UE), thus providing connectivitybetween the UE and the wider cellular network. The UE 102 can sendtransmission type recommendation data to the network node 104. Thetransmission type recommendation data can comprise a recommendation totransmit data via a closed loop MIMO mode and/or a rank-1 precoder mode.

A network node can have a cabinet and other protected enclosures, anantenna mast, and multiple antennas for performing various transmissionoperations (e.g., MIMO operations). Network nodes can serve severalcells, also called sectors, depending on the configuration and type ofantenna. In example embodiments, the UE 102 can send and/or receivecommunication data via a wireless link to the network node 104. Thedashed arrow lines from the network node 104 to the UE 102 representdownlink (DL) communications and the solid arrow lines from the UE 102to the network nodes 104 represents an uplink (UL) communication.

System 100 can further include one or more communication serviceprovider networks 106 that facilitate providing wireless communicationservices to various UEs, including UE 102, via the network node 104and/or various additional network devices (not shown) included in theone or more communication service provider networks 106. The one or morecommunication service provider networks 106 can include various types ofdisparate networks, including but not limited to: cellular networks,femto networks, picocell networks, microcell networks, internet protocol(IP) networks Wi-Fi service networks, broadband service network,enterprise networks, cloud based networks, and the like. For example, inat least one implementation, system 100 can be or include a large scalewireless communication network that spans various geographic areas.According to this implementation, the one or more communication serviceprovider networks 106 can be or include the wireless communicationnetwork and/or various additional devices and components of the wirelesscommunication network (e.g., additional network devices and cell,additional UEs, network server devices, etc.). The network node 104 canbe connected to the one or more communication service provider networks106 via one or more backhaul links 108. For example, the one or morebackhaul links 108 can comprise wired link components, such as a T1/E1phone line, a digital subscriber line (DSL) (e.g., either synchronous orasynchronous), an asymmetric DSL (ADSL), an optical fiber backbone, acoaxial cable, and the like. The one or more backhaul links 108 can alsoinclude wireless link components, such as but not limited to,line-of-sight (LOS) or non-LOS links which can include terrestrialair-interfaces or deep space links (e.g., satellite communication linksfor navigation).

Wireless communication system 100 can employ various cellular systems,technologies, and modulation modes to facilitate wireless radiocommunications between devices (e.g., the UE 102 and the network node104). While example embodiments might be described for 5G new radio (NR)systems, the embodiments can be applicable to any radio accesstechnology (RAT) or multi-RAT system where the UE operates usingmultiple carriers e.g., LTE FDD/TDD, GSM/GERAN, CDMA2000, etc.

For example, system 100 can operate in accordance with global system formobile communications (GSM), universal mobile telecommunications service(UMTS), long term evolution (LTE), LTE frequency division duplexing (LTEFDD, LTE time division duplexing (TDD), high speed packet access (HSPA),code division multiple access (CDMA), wideband CDMA (WCMDA), CDMA2000,time division multiple access (TDMA), frequency division multiple access(FDMA), multi-carrier code division multiple access (MC-CDMA),single-carrier code division multiple access (SC-CDMA), single-carrierFDMA (SC-FDMA), orthogonal frequency division multiplexing (OFDM),discrete Fourier transform spread OFDM (DFT-spread OFDM) single carrierFDMA (SC-FDMA), Filter bank based multi-carrier (FBMC), zero tailDFT-spread-OFDM (ZT DFT-s-OFDM), generalized frequency divisionmultiplexing (GFDM), fixed mobile convergence (FMC), universal fixedmobile convergence (UFMC), unique word OFDM (UW-OFDM), unique wordDFT-spread OFDM (UW DFT-Spread-OFDM), cyclic prefix OFDM CP-OFDM,resource-block-filtered OFDM, Wi Fi, WLAN, WiMax, and the like. However,various features and functionalities of system 100 are particularlydescribed wherein the devices (e.g., the UEs 102 and the network node104) of system 100 are configured to communicate wireless signals usingone or more multi carrier modulation schemes, wherein data symbols canbe transmitted simultaneously over multiple frequency subcarriers (e.g.,OFDM, CP-OFDM, DFT-spread OFMD, UFMC, FMBC, etc.). The embodiments areapplicable to single carrier as well as to multicarrier (MC) or carrieraggregation (CA) operation of the UE. The term carrier aggregation (CA)is also called (e.g., interchangeably called) “multi-carrier system”,“multi-cell operation”, “multi-carrier operation”, “multi-carrier”transmission and/or reception. Note that some embodiments are alsoapplicable for Multi RAB (radio bearers) on some carriers (that is dataplus speech is simultaneously scheduled).

In various embodiments, system 100 can be configured to provide andemploy 5G wireless networking features and functionalities. 5G wirelesscommunication networks are expected to fulfill the demand ofexponentially increasing data traffic and to allow people and machinesto enjoy gigabit data rates with virtually zero latency. Compared to 4G,5G supports more diverse traffic scenarios. For example, in addition tothe various types of data communication between conventional UEs (e.g.,phones, smartphones, tablets, PCs, televisions, Internet enabledtelevisions, etc.) supported by 4G networks, 5G networks can be employedto support data communication between smart cars in association withdriverless car environments, as well as machine type communications(MTCs). Considering the drastic different communication demands of thesedifferent traffic scenarios, the ability to dynamically configurewaveform parameters based on traffic scenarios while retaining thebenefits of multi carrier modulation schemes (e.g., OFDM and relatedschemes) can provide a significant contribution to the highspeed/capacity and low latency demands of 5G networks. With waveformsthat split the bandwidth into several sub-bands, different types ofservices can be accommodated in different sub-bands with the mostsuitable waveform and numerology, leading to an improved spectrumutilization for 5G networks.

To meet the demand for data centric applications, features of proposed5G networks may comprise: increased peak bit rate (e.g., 20 Gbps),larger data volume per unit area (e.g., high system spectralefficiency—for example about 3.5 times that of spectral efficiency oflong term evolution (LTE) systems), high capacity that allows moredevice connectivity both concurrently and instantaneously, lowerbattery/power consumption (which reduces energy and consumption costs),better connectivity regardless of the geographic region in which a useris located, a larger numbers of devices, lower infrastructuraldevelopment costs, and higher reliability of the communications. Thus,5G networks may allow for: data rates of several tens of megabits persecond should be supported for tens of thousands of users, 1 gigabit persecond to be offered simultaneously to tens of workers on the sameoffice floor, for example; several hundreds of thousands of simultaneousconnections to be supported for massive sensor deployments; improvedcoverage, enhanced signaling efficiency; reduced latency compared toLTE.

The upcoming 5G access network may utilize higher frequencies (e.g., >6GHz) to aid in increasing capacity. Currently, much of the millimeterwave (mmWave) spectrum, the band of spectrum between 30 gigahertz (Ghz)and 300 Ghz is underutilized. The millimeter waves have shorterwavelengths that range from 10 millimeters to 1 millimeter, and thesemmWave signals experience severe path loss, penetration loss, andfading. However, the shorter wavelength at mmWave frequencies alsoallows more antennas to be packed in the same physical dimension, whichallows for large-scale spatial multiplexing and highly directionalbeamforming.

Performance can be improved if both the transmitter and the receiver areequipped with multiple antennas. Multi-antenna techniques cansignificantly increase the data rates and reliability of a wirelesscommunication system. The use of multiple input multiple output (MIMO)techniques, which was introduced in the third-generation partnershipproject (3GPP) and has been in use (including with LTE), is amulti-antenna technique that can improve the spectral efficiency oftransmissions, thereby significantly boosting the overall data carryingcapacity of wireless systems. The use of multiple-input multiple-output(MIMO) techniques can improve mmWave communications, and has been widelyrecognized a potentially important component for access networksoperating in higher frequencies. MIMO can be used for achievingdiversity gain, spatial multiplexing gain and beamforming gain. Forthese reasons, MIMO systems are an important part of the 3rd and 4thgeneration wireless systems, and are planned for use in 5G systems.

Referring now to FIG. 2, illustrated is an example schematic systemblock diagram 200 of a new radio access architecture according to one ormore embodiments. 3GPP NR-based 5G mobile networks can be deployed usinga split RAN protocol architecture such that on the user plane the packetdata convergence protocol (PDCP) sublayers can reside at a centralizedunit (CU) 304, while the radio link control (RLC), media access control(MAC), and physical layer (PHY) layers can reside at the distributedunit (DU) 306. User plane data can be carried on data radio bearers(DRBs) that traverse the above described user plane RAN protocolarchitecture. On the control plane, signaling radio bearers (SRBs) canbe set up to carry control messages from the radio resource control(RRC) layer, also utilize the packet data control protocol (PDCP) layerat the CU, and are further carry the control messages down through theRLC, medium access control (MAC), and physical (PHY) layers at the DU306 to be delivered to the UE 102 over the air interface. Each networkuser can be allocated multiple DRBs and SRBs by the network. The networkinterface between the CU 304 and DU 306 can be called the F1 interfaceper 3GPP specifications.

Referring now to FIG. 3, illustrated is an example schematic systemblock diagram of integrated access and backhaul links according to oneor more embodiments. An IAB feature can enable future cellular networkdeployment scenarios and applications to the support wireless backhauland relay links enabling flexible and very dense deployment of NR cellswithout the need for densifying the transport network proportionately.

Due to the expected larger bandwidth available for NR compared to LTE(e.g., mmWave spectrum) along with the native deployment of massive MIMOor multi-beam systems in NR, IAB links can be developed and deployed.This can allow easier deployment of a dense network of self-backhauledNR cells in a more integrated manner by building upon many of thecontrol and data channels/procedures defined for providing access toUEs.

For example, the network 300, as represented in FIG. 3 with integratedaccess and backhaul links, can allow a relay node to multiplex accessand backhaul links in time, frequency, and/or space (e.g., beam-basedoperation). Thus, FIG. 3 illustrates a generic IAB set-up comprising acore network 302, a centralized unit 304, donor distributed unit 306,relay distributed unit 308, and UEs 102 ₁, 102 ₂, 102 ₃. The donordistributed unit 306 (e.g., access point) can have a wired backhaul witha protocol stack and can relay the user traffic for the UEs 102 ₁, 102₂, 102 ₃ across the IAB and backhaul link. Then the relay distributedunit 308 can take the backhaul link and convert it into differentstrains for the connected UEs 102 ₁, 102 ₂, 102 ₃. Although FIG. 3depicts a single hop (e.g., over the air), it should be noted thatmultiple backhaul hops can occur in other embodiments.

Referring now to FIG. 4, illustrated is an example user-plane protocolstack 400 according to one or more embodiments. FIG. 4 depicts a newprotocol stack layer, currently called an adaptation layer. Theadaptation layer at each IAB node 402, 404 can perform routing ofpackets across the IAB backhaul network. It can also perform amany-to-one mapping of UE bearers into a radio link control (RLC)channel across an IAB hop.

As depicted in FIG. 4, the protocol stack from the mobile termination(MT) of a serving IAB node 402 to the distributed unit (DU) of the donorIAB node 406 can comprise a general packet radio services tunnelingprotocol (GTP-U) layer, a user datagram protocol (UDP) layer, a securitylayer, an internet protocol (IP) layer, an adaption (adapt) layer, aradio link control (RLC) layer, a media access control (MAC) layer, anda physical (PHY) layer. The adapt layer can perform a routing functionfrom one IAB node (e.g., IAB node 402) to the IAB node parent 404, viathe adapt layer, while also communicating via the RLC, MAC, and/or PHYlayers. The IAB node parent 404 can then communicate this data to thedonor IAB node 406.

Referring now to FIG. 5 illustrated is an example schematic system blockdiagram of a data sequencing process 500 according to one or moreembodiments. When a UE 102 has data to send, it can send a schedulingrequest to the DU of IAB node 502 indicating that the UE 102 has data tosend. In response, the IAB node 502 can then issue an uplink (UL) grantrequesting how much data the UE 102 needs to send. Thereafter, the UE102 can send its BSR to the IAB node 502 to indicate to the IAB node 502how much data the UE 102 intends to send to the IAB node 502. Based onthis information, the IAB node 502 can issue a grant to the UE 102 basedon the size of the data (e.g., UE 102 grant is sized according to howmuch data is in the BSR). Then, the UE 102 can transmit its data on theuplink. The IAB node 502 can then begin this same process with anotherIAB node 504 to transmit the data from the UE 102 to the IAB node 504.Additionally, the IAB node 504 can complete the same process again totransmit the original data from the UE 102 to the IAB donor node 506.Because this transaction can occur over multiple hops, at each hop, theDU of the IAB node can receive the data originally transmitted from theUE 102 and the MT of the IAB node can send the data originallytransmitted from the UE 102 to another IAB node or the IAB donor node506. Thus, the IAB node 504 can send corresponding scheduling requeststo its parent node (e.g., IAB donor node 506), the IAB donor. However,this is performed only after the DU of the IAB node 504 has granted thedata exchange from its child IAB node (e.g., IAB node 502).

Referring now to FIG. 6 illustrated is an example schematic system blockdiagram of a pre-emptive data sequencing process 600 according to one ormore embodiments. However, as depicted in FIG. 6, this can be done inless time (e.g., via a different message sequencing pattern) instead ofwaiting for a disposition at each individual node. For example, the IABnode 502 can send the original SR from the UE 102 to the IAB node 504without waiting for the entire transaction to occur between the UE 102and the IAB node 502. Likewise, the IAB node 504 can send the originalSR from the IAB node 502 to the IAB donor node 506 without waiting forthe entire transaction to occur between the IAB node 504 and the IABnode 502, and so on and so forth with regards to the UL grants, BSR andPDUs at each IAB node. Thus, the time to complete the transactionbetween the UE 102 and the IAB donor 506 is less for FIG. 6 than it isfor FIG. 5, which can generate system efficiencies.

Referring now to FIG. 7, illustrated is an example flow diagram of asystem 700 that facilitates messaging for pre-emptive data processesaccording to one or more embodiments. In another embodiment, an IAB node502, 504, 506 can wait to send a pre-emptive trigger, it can send itimmediately, or it can send it based on a predetermined period of time.Consequently, the pre-emptive transmissions can be controlledaccordingly. For example, in some scenarios the pre-emptive sequencingcan be turned off if a feature needs to be tested for performance (e.g.,turned off to determine if the pre-emptive sequencing does indeedprovide a performance gain), if there is a performance issue and somevariability needs to be minimized, or if an IAB node from a vendor isnot performing well, the pre-emptive sequencing feature can be turnedoff such that the ill-performing IAB node does not utilize thepre-emptive sequencing feature. A gNB-CU-CP 702 can send a message tothe IAB node 502, 504. For example, the gNB-CU-CP 702 can send an on/offindication to the IAB node 502, 504, and based on that, the IAB node502, 504 can turn the pre-emptive sequencing feature one/offaccordingly.

Thereafter, the IAB node 502, 504 can send an acknowledgement that ithas received and/or complied with the message from the gNB-CU-CP 702.The pre-emptive sequencing feature can be controlled on a per IAB node502 basis and/or on an aggregate IAB node 502, 504 basis. For example,based on machine learning, the gNB-CU-CP 702 (e.g., network node 104)can determine if a certain area of the IAB node hierarchy is notperforming efficiently and/or if there are wasted resources and turn offthe feature in a certain area of the IAB node hierarchy. The messagingcan be over F1 access point (AP) directly to the DU and/or sent via aradio resource control (RRC) message to the MT of the IAB node 502, 504.There can also be a lower layer indication (e.g., layer 1 downlinkcontrol information (DCI) signaling or a layer 2 media access control(MAC) control element (CE) signaling), which is provided from the parentIAB node (e.g., IAB node 504) to the child IAB node (e.g., IAB node 502)to turn the feature on/off, thus giving the parent IAB node (e.g., IABnode 504) an opportunity to control the feature based on its perspectiveof the network performance.

When used in either a LAN or WAN networking environment, the computer1202 can access cloud storage systems or other network-based storagesystems in addition to, or in place of, external storage devices 1216 asdescribed above. Generally, a connection between the computer 1202 and acloud storage system can be established over a LAN 1254 or WAN 1256e.g., by the adapter 1258 or modem 1260, respectively. Upon connectingthe computer 1202 to an associated cloud storage system, the externalstorage interface 1226 can, with the aid of the adapter 1258 and/ormodem 1260, manage storage provided by the cloud storage system as itwould other types of external storage. For instance, the externalstorage interface 1226 can be configured to provide access to cloudstorage sources as if those sources were physically connected to thecomputer 1202.

Wi-Fi, or Wireless Fidelity, allows connection to the Internet from acouch at home, a bed in a hotel room, or a conference room at work,without wires. Wi-Fi is a wireless technology similar to that used in acell phone that enables such devices, e.g., computers, to send andreceive data indoors and out; anywhere within the range of a basestation. Wi-Fi networks use radio technologies called IEEE 802.11 (a, b,g, etc.) to provide secure, reliable, fast wireless connectivity. AWi-Fi network can be used to connect computers to each other, to theInternet, and to wired networks (which use IEEE 802.3 or Ethernet).Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands, atan 11 Mbps (802.11a) or 54 Mbps (802.11b) data rate, for example, orwith products that contain both bands (dual band), so the networks canprovide real-world performance similar to the basic 10BaseT wiredEthernet networks used in many offices.
